Contact-electro-catalysis (CEC) is a bridging concept between contact-electrification effect (also known as triboelectricity) and mechanochemistry. It was first proposed in 2022 by using dielectric materials (e.g., FEP) to catalyze the degradation of methyl orange (MO) aqueous solution.[1] The definition of CEC refers to a process that exploits the electron transfer during contact-electrification (CE) to promote chemical reactions.[1] The solid to be used in CEC involves pristine polymers (FEP, PTFE),[2][3][4] inorganics (SiO2),[5][6] and matrix composites.[7][8][9] The energy source of CEC is mechanical stimuli such as ultrasonication and ball milling.[1][2][10] The application fields of CEC include organic pollutants degradation,[1][6] [11][12] direct synthesis of H2O2, [13][14] recycle of spent lithium-ion batteries (LIBs), [5] and continuous synthesis of ammonia.
